Lead poisoning (铅中毒)occurs when lead is present in high levels in the blood of a person.It is one of the most common medical problems found in children.And it's important to recognize the presence of lead in children's bodies because lead is very harmful.
Children have the tendency to go around and put things in their mouths like paint peelings.This is one of the main causes of lead poisoning.It has also been found that children born in poor families have higher chances of getting exposed to lead.
Some of the common symptoms of lead poisoning in children are headaches，stomach pains，hair loss，muscle weakness，and weight loss，etc.
Lead poisoning can have severe effects and can lead to heart diseases，kidney diseases and neurological(神经系统的) problems.It can also result in mental dullness and a low IQ level.There have been cases where lead poisoning proved to be terminal for children.
It's difficult to easily recognize whether a child is affected by lead poisoning，as the symptoms of this disease can occur due to some other medical problems.Therefore，children under the age of 6 should regularly be checked to know the level of lead in their blood through blood tests.It's possible to completely cure a child with lead poisoning through treatment.Usually the oral medicine chelator(螯合剂)is given to the children.Sometimes，children are given an injection(注射) for reducing the lead level.Children who have very high level of lead in their blood would need treatment for a long period of time and would also be put on a special diet.
Parents have to take certain precautions to lower the chance of lead poisoning in children.Cleaning the house regularly and removing shoes at the door after coming in from outside will prevent the lead particles from entering the house.Children should be put on a healthy diet，containing high proportions(比例)of calcium and iron，such as eggs，milk，fruits，potatoes，etc.which helps to keep the lead levels in control，in the children's bodies.
In short，it's a must to be cautious and careful，and protect your children from the horrible consequences of lead poisoning.

For 800 years Oxford and Cambridge universities have competed in everything from Nobel Prizes to boat races.The academic competition runs deep: Oxford has tutored 25 British prime ministers，while Cambridge claims Darwin and Newton as its own.But today the well­known universities launch into battle on iTunes，taking their ancient competition into the 21st century.
The universities are meanwhile publishing about 450 hours of free audio and video clips of lectures，films and admissions guides for people to download to a computer or MP3 player.They will also provide podcasts(播客)advising students on applications，how to choose a college，and how to prepare for an interview.
They deny the launch at the same time is designed to start an iTunes race，instead claiming it is a sign they are opening up to a wider audience.John Hood，Oxford's vice­chancellor (副校长)，said: “We hope that this service will make Oxford's diverse range of audio and video material more widely accessible to applicants，alumni (校友)，supporters of the university，and the intellectually curious.” And Greg Hayman，head of communications at Cambridge，claims: “It's not just for students and potential students but for the wider public.”
However，it will undoubtedly invite accusations(责怪) of a new battleground for the famous rivals(竞争对手)．After eight centuries the competition between them is fairly even：Oxford has produced more prime ministers but Cambridge claims more Nobel Prize winners.So who is the winner in the wave of electronic competition? Let's wait and see.
1. What battle do the two well­known universities launch into? (No more than 4 words)

答案　iTunes/Electronic competition.
2 What do they claim the launch is intended for? (No more than 7 words)

答案　The competition is one equally winning/neck and neck.
4. What is the passage mainly meant to tell us? (No more than 12 words)

答案　The competition between the two universities is expanding to a new battleground.
